What would your feature do ?

The generated PNG images include embedded details of the parameters used to generate them, as shown if you drag an image into the "PNG info" tab. The fact that the "Accelerate with OpenVINO" script was used doesn't seem to be recorded; if you look at the two attachments for https://github.com/openvinotoolkit/stable-diffusion-webui/issues/43, the "PNG info" tab shows the same for both.

Since it can make a difference to the results (particularly if a feature not supported by the "Accelerate with OpenVINO" script is used), I think it would be nice if the generated image included this information.

Proposed workflow

1. Generate an image using "Accelerate with OpenVINO"
2. Drag the image onto the "PNG info" tab
3. The displayed information includes an indication that "Accelerate with OpenVINO" was used.
